Do the raised tracks or flutes inside the vintage Dukoff FLUTED hard 
rubber mouthpiece floor and chamber as well as the Sugal mini-tracks 
really serve any acoustical purpose or are these just a gimmick?

My only thought on it is that Dukoff bailed on the fluted chamber and  
offered an non-fluted version, and Sugal has not gotten a foothold  
despite the mini-tracks.

My guess is that they are just a gimmick. There would be some change acoustically, though, since the fluting would increase the surface area of the walls and thus actually add to acoustic losses in the mpc through the boundary layer effect (where air molecules close to the walls are slowed down and lose energy to the walls). The goal is to have the smoothest walls possible, at least in terms of acoustic efficiency. If you want to work harder for less then the fluting would be for you ;-)
